Hell Gate

Hell Gates allow demons to travel from the Underworld to the Human World. Two millenia before Devil May Cry 4, Sparda used the Yamato to seal the true Hell Gate.

The true Hell Gate and three lesser gates feature prominently in Devil May Cry 4, in which Agnus uses the Yamato to open them and allow demons into Fortuna. The three lesser gates, located in the outskirts of the island, allow Berial, Echidna and her children, as well as Bael, Dagon, and their kin into Fortuna.

After subduing Nero in the Containment Room, Agnus explains that he created the three lesser Hell Gates as substitutions for the true Hell Gate, and by using remnants of the "Dark Angel" and an "extremely powerful Devil's Arm", they had proved sufficient.

Nero closes the gates as he chases Dante, and as Dante returns to Fortuna to battle the Savior, he kills the escaped demons and uses the Devil Arms they relinquish to destroy the Gates. After Dante returns to the true Hell Gate, he battles Agnus and retrieves the Yamato, which he uses to destroy the final gate.
